This is my first attempt at using the REW program. I took my measurements with the Radio Shack digital SPL meter ( C weighted fast) on a tripod at the listening postion. Measurements were made in 1 Hz increments from 10-109 Hz with the Real Traps tones burned onto a disc. Target volume was 75 dB. The data was typed into the computer and saved as a comma delimted file. Overall I think it looks pretty good really. This is the sub plus mains, with no room treatments. The crossover is set at 50 hz(although the graph is actually set a 80 Hz). It sounds quite good. The Ultra is a great sub! THis is 15Hz tuning
Let me know what you think.
